It's apparently a Cantonese phrase, used frequently in Digimon by Terriermon so it's probably been assumed it's Japanese by most viewers....

Best description I could get was on about.com

Terriermon is of an over-confident sort and tends to have sarcastic remarks to people, especially his partner. He likes to use the term "moumantai" (which can be written as沒問題 or没问题), a Cantonese phrase that means "take it easy" or "no problem".

You know, when you said Cantonese it clicked. The old romaji problem -- when I know what I'm looking at, I "hear" it differently in my head, and I hear 沒問題 in the sing-song tones of Cantonese. Of course, if I *saw* 沒問題 I'd want to read it as mei wenti, but that's because I actually studied Putonghua rather than Kandonghua...
